Definitions
- the present invention relates to an implant with a surface structure, in particular to a transcutaneous implant with a directional structure on the surface, which improves the ingrowth behavior of the implant and a method for producing such an implant.
- Implants which are fully or partially inserted into a body, with an area of the port body protruding from the skin surface, for example, when a port body is used. Problems often arise when the surrounding skin grows onto the port body. Inflammation often forms in the border area between the surrounding skin and the port body, which spreads along the port body used into a patient's body. This is uncomfortable for a patient and leads to poor fit of the port body and a high risk of infection for the patient.
- a device for promoting wound healing which consists of a biologically compatible material and is biodegradable.
- This device is used for wound healing in the wound and has a surface structure which serves to orientate a desired cell growth and can be biodegraded during or after use, that is, it can be resorbed by the patient.
- the implant according to the invention is preferably a transcutaneous implant, i. H. an implant that is not fully inserted into a body, so that after the implant is inserted, at least a part protrudes from the skin surface, such as, for example, in a port body that is used to introduce a substance into a tissue located below the skin surface.
- a surface structure is provided on at least one surface area of the implant, which improves the ingrowth behavior of the implant.
- the surface structure is preferably directed in such a way that the growth of cell tissue lying around the implant is promoted and / or supported in one or more specific preferred directions.
- the surrounding tissue can be, for example, skin cells, muscle cells or blood vessels.
- the resulting cell arrangement promoted by the surface structure leads to accelerated wound healing and to an improved connection between the surrounding tissue cells and the implant wall, in particular the structured area of the surface of the implant.
- Such an improved connection between the surrounding tissue cells and the implant also leads to improved protection against bacteria and undesired substances, so that the risk of infection and inflammation when inserting the implant can be reduced.
- a suitable surface structure can achieve a denser colonization of the implant surface by the surrounding tissue and thus an improved adhesion of the cells to the implant wall.
- the implant is preferably made at least in part from a durable, non-absorbable material, such as metal or plastic, or combinations thereof, so that the implant is not disassembled after insertion.
- the implant advantageously has a suitable surface structure in the area of the skin penetration, the surface structure particularly preferably running approximately parallel to the skin surface in the inserted state of the implant.
- a surface structure which promotes the growth of cell structures in particular blood vessels parallel to the existing tissue, for example parallel to the skin surface, also leads to the fact that the blood vessels accumulate mainly parallel to the skin surface around the implant and away from the implant and essentially do not reach deep along the implant wall.
- Such an arrangement of the blood vessels around the implant leads to better blood circulation in the surrounding tissue and is furthermore advantageous since infections which may occur on the skin surface can only propagate with difficulty in deeper regions along the implant wall. Infections can therefore be combated more efficiently by the body's own defenses and continue to be recognized earlier by the patient.
- the structure on the surface of the implant is advantageously 1 to 10 mm wide, particularly preferably 4 to 5 mm wide, so that tissue surrounding this preferred width of the surface structure in the inserted implant at a depth of 1 to 10 mm, preferably 4 to 5 mm oriented and directed to the implant.
- the surface structure is advantageously arranged circumferentially around at least a partial area of the implant, for example in the case of a circular or oval cross section of the implant in the area of passage through the skin surface as a groove structure encircling the implant, which preferably has a uniform orientation, i. H. the individual grooves are preferably approximately parallel to one another.
- the surface structure is particularly preferably designed as a groove structure, for example as a circumferential spiral or helical groove.
- the surface structure can only be provided on certain areas of the implant Other surface areas of the implant have no surface structure, so that, for example, only individual grooves or groove structure sections are provided on the implant surface, which, for example, are broken through by a smooth implant surface if, for example, a desired orientation of the cell growth only in one area of the implant surface it is asked for.
- the depth of the grooves is preferably in the range of 0.1 to 10 times, particularly preferably in the range of 0.3 to 5 times, the average width of the cell type which is to grow on the groove, with the below the average width of the cell type Width is understood when the cell is placed on a flat surface.
- the depth of one or all grooves is advantageously in the range from 1 to 10 ⁇ m, preferably in the range from 3 to 4 ⁇ m.
- the width of a groove is advantageously in the range from 1 to 10 ⁇ m, particularly preferably in the range from 4 to 5 ⁇ m.
- the groove spacing i.e. H. the distance from the center of the groove to the center of the groove is advantageously in the range from 2 to 20 ⁇ m and is preferably 10 ⁇ m.
- the ratio of the width of the groove to the depth of the groove is advantageously in the range from 0.5 to 2, preferably essentially 1: 1.
- At least two, preferably three to ten or more areas with a different surface structure are preferably provided on the implant surface, so that, for example, a first surface structure is provided in the area near the skin surface when the implant is used, in order to enable the growth of skin cells and one or more other surface structures are provided below this first surface structure, which promote the growth of cell structures lying under the skin surface, such as blood vessels or the like.
- a lower holding structure is advantageously provided on the implant, which is inserted into the tissue and is, for example, a ring which runs around the underside of the implant and protrudes from the implant in order to promote the hold of the inserted implant.
- passages or holes can advantageously be provided at one or more points on the circumferential ring, through which tissue can grow in order to promote a better fit of the implant.
- a recess for example a groove, into which surrounding tissue can grow, can advantageously be provided in the attachment area of the circumferential ring, so that the fit of the implant is further improved.
- the implant is preferably a transcutaneous implant, such as a port body, and has a connection structure, such as a thread or suitable holding elements, such as in the upper region, that is to say, for example, in the region that protrudes from the tissue when the implant is in the inserted state for example depressions with projections on which a connecting element can be attached in order to be able to introduce a substance from an external source through the port body into a tissue from the outside, the port body for example having an opening on its underside through which a substance introduced from the top enters the tissue.
- a connection structure such as a thread or suitable holding elements, such as in the upper region, that is to say, for example, in the region that protrudes from the tissue when the implant is in the inserted state for example depressions with projections on which a connecting element can be attached in order to be able to introduce a substance from an external source through the port body into a tissue from the outside, the port body for example having an opening on its underside through which a substance introduced from the top enters
- a method for producing the implant described above is proposed, a surface structure which improves the ingrowth behavior of the implant being produced on at least a partial area of the surface of the implant.
- This spiral groove can, for example, be produced in a single pass using a specially ground shaped steel. It is advantageous for the implant to be created after the groove has been created along the groove Polish groove or creases so that the surface becomes essentially smooth. The grooves are rounded off, but are still retained.
- the implant can then advantageously be anodized or anodized, an oxide layer being formed which also extends over the structured area of the implant.
- etching process in order to produce a desired surface structure, for example by means of an applied etching mask.
- Surface areas that should not be etched are protected with an acid-resistant layer.
- a multitude of different surface structures can be produced in one operation using an etching process.
- Figure 1 shows an implant with an enlarged portion of the surface
- FIG. 2 shows a port body used in the tissue with a surface structure according to the invention.
- FIG. 3 is an enlargement of a portion of that shown in Figure 2
- FIG. 1 shows an implant 1 which has a structured surface area 2 in the form of circumferential grooves on an area of the implant wall 4. If the implant 1 is inserted into the tissue in such a way that the grooves 2 lie in the area of the skin surface and essentially parallel to the skin surface, the circumferential grooves can promote the growth of the skin cells in one direction along the grooves and thus for better ingrowth and a more secure hold of the implant.
- FIG. 2 shows a port body 1 inserted into a fabric with a circumferential surface structure 2 in the form of a circumferential spiral groove.
- tissue cells such as skin and muscle cells, cells as well as blood vessels 6 along the directed groove structure 2, whereby a dense colonization of the port body surface 4 by the tissue 3 can be achieved parallel to the skin surface.
- tissue cells such as skin and muscle cells, cells as well as blood vessels 6 along the directed groove structure 2, whereby a dense colonization of the port body surface 4 by the tissue 3 can be achieved parallel to the skin surface.
- tissue cells such as skin and muscle cells, cells as well as blood vessels 6 along the directed groove structure 2
- Such a denser colonization by tissue cells leads to an improved connection, ie to a better ingrowth of the surrounding tissue 3 in the port body 1, as a result of which the port body 1 can be held more securely and firmly.
- the cell structure thus aligned by the circumferential groove structure 2 also stimulates the blood vessels 6 to orient themselves parallel to the existing tissue 3, so that the blood vessels 6 predominantly run parallel to the skin surface 5 around the port body 1. This promotes blood circulation in the tissue area surrounding the port body 1 and largely prevents the spread of an infection into the depth of the tissue.
- an essentially smooth implant wall 4 is formed, on which the surrounding tissue simply grows or rests, as is known in the case of the implants from the prior art.
- a ring 7 which extends around the underside of the port body 1 and ensures a better hold of the inserted implant 1 in the tissue 3.
- the ring 7 is interrupted by a plurality of holes 8, through which tissue 3 can grow, in order to hold the port body 1 in the tissue 3 continue to improve.
- a groove is provided, into which tissue 3 can grow.
- the area of the port body 1 protruding from the tissue on the skin surface 5 has a connection structure (not shown) to which a connection element 10 can be attached in order to introduce a substance from an external storage container through the implant body 1 into the tissue 3.
- the port body 1 may have an opening (not shown) on its underside through which the substance is released from the port body 1 into surrounding tissue.
